Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
yes

method according to Siwoloboff
Specific details on test material used for the study:
Component of a Polyurethane System

Key result
Decomposition:
yes
Remarks:
(discolouration of test material)
Decomp. temp.:
236 °C

The sample started to discolour at 235°C (run 1) and 236°C (run 2), therefore the test was terminated and the boiling point could not be determined.

Conclusions:
The decomposition temperature of the substance was estimated to be 236 °C and the boiling point could therefore not be determined.

Description of key information

The decomposition temperature of the test substance was determined to be 236°C, following EU test method A.2, using the Siwoloboff method (Baker, 2010)

Key value for chemical safety assessment

Additional information

The sample started to discolour at 235°C (run 1) and 236°C (run 2), therefore the test was terminated and no boiling point could be determined. The discolouration was considered as a sign of decomposition, therefore the decomposition temperature was concluded to be 236°C.
